Expansion joint filling material



Patented Jan. 8, 1935 -gnutrail .flfhis invention relates generally tomaterials. fonfill-ing.expansiomjoints andparticularly to an;improvement in .such. materials which I results in, itshavingthe-.features ofnovelty and advantage ;set.out intdetailwbelow. i

..I-t:is an;. object of this invention to provide material of the typedescribed which will not only.

fulfill; the ;.ord-inary requirements of a 3 material of-"thisgcharacter, but whichuwill have the ad-- I ditional advantagesof-remaining soft and pliable at -.very 'lowtemperatures, and remainingplastic and full bodied atftemperatures eranging ,up to.-

200 degrees Fahrenheit.

.. Itis also an object of this invention to provide armaterial'of thecharacter described which will haveyvery-little variation at highand-low temperatures as respects a penetration .test, inc0n-,- trasttothe extensively used asphalt and tar materials which show under thepenetration test,

. impenetrability at low temperatures and complete loss oft-plasticityandelasticityand body at ping at :low temperature, since at ,low temperatures itretains itssoftness and pliability as well as elasticity. It isa,further-objec;t of ethis invention to provide amaterial ofthecharacter described whichis adaptable totakertheplace of suchmaterials and structures whichhave heretofore'been used. particularly infilling the expansion joints in roads;

particularly ot-the concrete type, but which may be -.used in any placeor structure requiring a resilient, elastic,- andplastic material, whichwill retainzits form andcondition in spite of variations,

. within wide ranges of temperature.

It .is :also anyobject of this invention to provide a material of thecharacter described which is ideally adapted to function as a filler forthe expansion joints of concrete road constructions and which at hightemperatures may be poured into the said expansion joints and which uponcooling, forms the required weatherproof and moisture-proof jointresponsive to the expanding and contracting movement of the concrete andthe like constituting the joint.

It is a further object of this invention to provide a material of thetype described which is composed of a new and novel combination ofelements, which renders the material more satisfactory, more durable,and above all more easily applicable than known similar substances, andhence saving of labor and' expense' irr'theliconstruction of roads, andother structuresirequiring a joint filler of the general type al-ludedto."

These and other objects of the i nventioni, its natui'e,' and itscomp'osition:--and-- arrangement and combination of parts will bereadiIy u nderstood by -'any one---acquainted withthe art to which thisinvention relates upon-consulting the. following descriptions andexplanations.

It should beunderstood that various other types ofexpansion joints, not included in the concept of concrete road expansionjoints, may be successfully packed with my improved material, at a lessexpense for installation and for upkeep.

A soft, elastic, plastic, pliable, material having the resistive qualitynoted above is, according to my invention produced by oxidizing andvulcanizing vegetable and fish oils, such as olive oil, corn oil, palmoil, rapeseed oil, fish oil, linseed oil, cotton seed oil, menhaden oilor any unsaturated fats or fatty oils capable of being oxidized orvulcanized. The use of any or a combination of .any

ate n 5' dint " m nt orth manta;

of the above oils and fats, may be selectively made with a view toemploying the least expensive thereof, whereby the cost of the finalproduct may be reduced, and its use thereby rendered more economicalthan in the case with the well known asphaltum, tar, and hydrocarbonmaterials now in extensive use for the same or for similar purposes. litwill be observed that some of the above oils, knowfri in the} art:asig'dr'yin'g, or semidryingmils, such as particularly cottoiiseed oil,linseed oil, and rapeseed oil.

A very satisfactory formula for use in making" erations, within thespirit and scope of the invention.

What is claimed is:-

1. An expansion joint filling material which retains substantially itsplasticity, body, and cohesiveness at temperatures ranging from to 200Fahrenheit, comprising the reaction product of substantially equalproportions of vegetable oil, of drying oil, and of 'a vulcanizingagent; and substantially smaller proportions of rosin and of silica, andabout 3% of blown asphalt.
